It features a local LCD display which provides irrigators with the ability to control the service point and view instantaneous flow rate, volume of current delivery, and total flow volume for the season.

The SlipMeter can be managed and monitored on-site or operated remotely when connected to a SCADA network such as Rubicon’s SCADAConnect® system.

The SlipMeter is ideal for

Measuring and controlling flow in farm service points

Channel-to-pipe applications especially when large conduits are used

Applications affected by turbulence

Lowering civil costs because there is no need to stabilise flow at entry and exit

SCADA ready communication system – can be integrated to many SCADA platforms

Robust high duty cycle operation and long life

Flow measurement accuracy is not affected by obstructions, turbulence, or contaminants

Independently verified flow measurement accuracy of ±2.5%*

Standard sizes include 600, 750, 900 and 1200mm

Very low power consumption compared to magnetic flow measurement

Control capabilities

The SlipMeter automatically controls the flow of water by varying the gate position based on a desired set-point or on irrigation demand as shown in the table.

Control objective

Gate action

Local

Position

Moves to a desired set-point and stays there

Flow

Maintains a constant flow regardless of channel level

Local control pedestal

Each SlipMeter installation includes a robust pedestal that provides power and control to the gate and is a secure, weather proof housing for electronic components and batteries.

The pedestal also serves as a local user interface. A keypad and LCD display are located under the lockable pedestal lid, allowing farmers to monitor, or operators to control and troubleshoot on-site.

Low maintenance

The SlipMeter’s modular design allows it to be maintained in the field with minimal tools, training, and easily replaceable parts.

Level sensors are easily removed during in-field servicing

Seals can be replaced

On-site diagnostics built into the software

Service can be done by local Rubicon field technicians or authorised/trained independent local integrators

Easy to install

Rubicon’s SlipMeters are designed to mount to existing headwall structures as well as purpose built emplacements significantly reducing costs associated with civil work.

Installed and operational in two days during irrigation or off-season

Factory calibrated and pre-configured

Existing manual gate

Replaced with SlipMeter

Independently tested flow measurement accuracy

The SlipMeter’s flow measurement accuracy has been independently verified under a wide range of conditions in the laboratory and in the field:

Technologies

The SlipMeter uses technologies developed by Rubicon which are common across TCC® products:

Sonaray® flow measurement

The SlipMeter employs Sonaray ultrasonic array technology. The ultrasonic array principle maps the velocity profile by using multiple transecting paths to provide an accurate representation of the velocity distribution within the meter box.

This technique measures across the entire velocity field within the meter box and is resistant to swirl, or other non-uniform velocity distributions caused by garbage or other debris.

Each measurement plane implements crossed-path transit time acoustics to sample the entire velocity field in that plane (plan view of measurement plane)

The horizontal velocity distributions are then integrated vertically to construct the three dimensional flow velocity distribution (side view)

High-strength FormiPanel™ construction

The SlipMeter features FormiPanel™, Rubicon’s high-strength construction method that uses techniques adopted from the aerospace and marine industries.

The gate panel and meter assembly is made from a laminate construction that utilises high strength industrial adhesives to bond structural grade aluminium extrusions and skin plates to a synthetic core material. The result is strong, lightweight, and corrosion resistant.

CableDrive™ and SolarDrive® gate control technology

CableDrive is Rubicon’s actuation system designed to provide precision gate position accuracy and repeatability in harsh environments. The drive is a wire rope (cable) and drum mechanism that provides positive drive in both the raise and lower directions. It is designed for high duty cycle operation and provides precise gate positioning to within ±0.5mm.

The drive is managed by Rubicon’s SolarDrive technology – a purpose built integrated circuit board that manages gate positioning, solar power regulation, battery charge, fusing and the pedestal user interface.
